Mac and I continue our discussion about survival tactics, and then he tells a story about his most famous boss, Sir Ranulph Feinnes, the world's greatest living explorer.

Mac Mackenney is probably the most experienced adventurer that I have ever met, a true professional, and owner of Max Adventure (http://www.maxadventure.co.uk). He has been Sir Ranulph Fiennes’ (http://www.ranulphfiennes.co.uk/) right hand man for decades, and lives at the extreme edge of survival adventure. I was privileged to interview Mac in late 2016.
